I just reviewed draft-ietf-trill-transport-over-mpls-01, with particular attention to the pseudowire encapsulation used in sections 3.4 and 4.3. While technically correct, the details were a bit on the sparse side, especially for section 3.4. I’ve got some suggested replacement text:
Section 3.4: Use of VPLS [RFC4762] to interconnect TRILL sites requires no changes to a VPLS implementation, in particular the use of Ethernet pseudowires between VPLS PEs. A VPLS PE receives normal Ethernet frames from an RBridge (i.e., CE) and is not aware that the CE is an RBridge device. As a result, an MPLS-encapsulated TRILL packet within the MPLS network will use the format illustrated in Appendix A of [RFC7173]. Section 4.3: The VPTS model uses PPP pseudowires for MPLS encapsulation as specified in [RFC7173], and requires no changes in the packet format in that RFC. The existing section titles are fine. Thanks, Andy
